WARNING
The following test involves the use of intense heat. Failure to follow appropriate
procedures or warnings can cause burns can result in severe personal injury. While
performing the following test, observe these precautions:
•
Wear personal protective clothing such as rubber gloves, a non-flammable
apron, and eye protection - preferably full face shield or safety glasses.
•
The appropriate heat source should be electric. Heat source should be operated
by a qualified person. Be sure to follow all instructions of the manufacturer of
the heat source. The heat source should be checked each time it is used to be
sure it is functioning properly.
•
The thermometer used in the test should be a high-temperature thermometer
with a maximum reading of at least 300°F (150°C). Under no circumstances
should the operator allow temperatures to exceed test specifications.
•
•
Perform test only in a well ventilated area.
Use a suitable container, such as metal, to hold the sand. Avoid use of glass
containers unless the operator first confirms for himself/herself that the glass
container is an appropriate high-temperature vessel.
•
Because the components will reach high temperatures DO NOT handle
materials or components until COMPLETELY cooled.
WARNING
Use only clean, dry sand such as used for general sandblasting purposes. Use of
sand containing contaminants could result in hazards such as fire, short circuiting,
hot-spots or other hazards.

With an ohmmeter connected as outlined and using suitable container, thermometer
and heat source, suspend sender with tip in sand.
